Talking Under Water

A lively WEFTEC 2026 recap explores AI’s expanding role in water utilities, from practical applications and governance to data-center demand and AI-generated public-records requests. The discussion also covers cybersecurity readiness, utility financing and federal funding, a solids-handling pump innovation, and creative public outreach for potable reuse.

In this episode Talking Under Water host Mandy Crispin discusses the upcoming water reuse regulatory guide, an effort led by the Water Reuse Association to help states develop or modernize water reuse regulations. Joined by Bruno Pigott, executive director of the association, and Tricia Kilgore of Beaufort Jasper Water and Sewer Authority, the conversation explores why the guide was created and how it can help states navigate the often complex process of adopting reuse regulations. The guests explain that water reuse regulations vary widely across the United States, creating challenges for communities looking to expand reuse programs. Drawing from lessons learned during rulemaking efforts across multiple states, the guide provides flexible pathways that can be adapted to existing legal and regulatory frameworks rather than prescribing a one-size-fits-all approach. Kilgore shares South Carolina's experience pursuing expanded reuse opportunities and discusses how treated effluent should be viewed as a valuable resource rather than a waste product. The discussion also examines the importance of identifying local drivers for reuse, engaging regulators and stakeholders early, addressing fragmented regulatory authority, and building public understanding throughout the process. The episode concludes with lessons from the guide's development involving more than 200 stakeholders, highlighting collaboration, public health protection, and long-term planning as essential ingredients for advancing water reuse projects and regulations nationwide.

In this episode, Talking Under Water co-host Bob Crossen discusses advanced metering infrastructure (AMI), data management, utility modernization, stakeholder buy-in, and the future of smart water utilities with Kamstrup Solutions Engineer Jake Waidmann. The conversation explores how utilities exist across a wide spectrum of metering technology adoption, from manual meter reading to next-generation AMI systems, and why technology decisions should be driven by operational challenges rather than by features alone. Jake explains how utilities can identify the right data to collect, use metering information to reduce non-revenue water, improve leak detection, and justify investments through measurable return on investment. The discussion also examines the growing volume of utility data and the importance of retaining, organizing, and applying that information to support rate studies, conservation initiatives, and long-term planning. Jake highlights the need to involve a broad range of stakeholders, including operators, customer service teams, managers, executives, consultants, and governing boards, when implementing new technologies. He emphasizes that successful adoption depends on building trust in both the data and the systems generating it. Looking ahead, Jake shares his vision for the smart water utility of 2030, centered on three key pillars: proactive operations, data-driven decision-making, and continuous improvement. Together, these principles can help utilities maximize system performance, improve customer service, and make more informed infrastructure investments.  Show notes Kamstrup  Timestamps 00:00 – Introduction 02:00 – Meeting utilities where they are on the AMR-to-AMI journey 05:02 – Why solving problems matters more than collecting more data 08:15 – Managing, storing, and using utility data effectively 13:40 – Building trust and managing organizational change during AMI adoption 19:18 – Gaining buy-in from operators, managers, executives, and boards 23:47 – The future of smart water utilities: proactive, data-driven, continuous improvement 28:48 – Housekeeping   About the Podcast     Talking Under Water is the premier podcast for the water industry, including municipal water and wastewater, residential water treatment, storm water management and erosion control.
